JAMES FINDLAY, OF TORONTO, CANADA, ASSIGNOR TO HIMSELF AND WILLIAM SMELLIE, OF SAME PLACE.

IMPROVEMENT IN VISES.

Specification forming part of Letters Patent No. 109,121, dated November 8, 1870.

I, JAMES FINDLAY, of the city of Toronto, in the county of York, Province of Ontario, and Dominion of Canada, have invented a certain Improvement in Vises, of which the following is a specification:

Nature and Objects of the Invention.

My invention is an improvement in vises; and consists in aftxing to them adjustable jaws, in order that beveled work may be held lnore securely, the said adjustable jaws adapting themselves to the bevel, as I will describe further on.

Description of the Accompanying Drawing.

General Description.

I make thc adjustable jaws A and B of either iron or steel, and shape them as represented by drawing. The forceps, or, in other words, the head of the vise, must, of course,

have grooves cut in them to correspond with the adjustable jaw intended for each headfi. e., A cut to t O, and B to tD. Eachjaw, A and B, its into its appointed place, and, if found necessary, may be held there by small steel pins inserted in a suitable manner.

By referring to Fig. V, it will be seen that one side of the forcep or vise-head is beveled at E. The object of this is to permit the adjustable jaw B to adaptitself to a wedgeshaped piece of work when held across the vise, the thick part of the wed ge being at the same side of the vise, as E. A parallel piece of work may be held equally as well, the opposite side of the vise F not being beveled.

In Fig. VI it will be seen that the forcep on vise-head B is beveled at the top and bottom edges. jaw to adapt itself to a piece of work which is thicker at one end than the other.

I do not claim all forms of adjustable jaws for vises 5 but I do claim as my invention- The peculiar construction of the jaws A B and their application to the forceps or visejaws O D, substantially as herein set forth and shown.
